Picture of Chalazion (Eyelid Cyst)
A chalazion is a bump or cyst that forms on an upper or lower eyelid due to a blocked oil gland (meibomian gland). Chalazions may range in size from very small and barely visible up to the size of a pea. These growths usually resolve without treatment within a few weeks to a month. Application of a warm compress several times a day to the affected area may help speed healing. The chalazion will eventually drain and heal. A doctor may prescribe antibiotic drops or ointment to help guard against infection. In some cases, a doctor may surgically remove a chalazion that is not healing.
